Streptomyces Sannurensis Sp. Nov., a New Alkaliphilic Member of the Genus Streptomyces Isolated from Wadi Sannur in Egypt

Accepted 19 April, 2011 The taxonomic position of an actinomycete isolated from a soil sample collected from Wadi Sannur in Egypt was established using a polyphasic approach. The isolate, which was designated WS 51T, was shown to have chemical and morphological properties typical of streptomycetes. An almost complete 16S rDNAgene sequence of the strain was generated and compared with corresponding sequences of representative streptomycetes. The resultant data confirmed the classification of the strain in the genus Streptomyces but also showed that it formed a distinct phyletic line within the 16S rDNAStreptomyces gene tree. The organism was most closely associated to the type strains of Streptomyces hygroscopicus, Streptomyces malaysiensis and Streptomyces yatensis but was readily separated from them using a range of phenotypic properties. It is proposed that strain WS 51T (= CCTCC 001032T = DSM 41834T) be classified in the genus Streptomyces as Streptomyces sannurensis sp. -

Streptomyces Cytochrome P450 Enzymes and Their Roles in the Biosynthesis of Macrolide Therapeutic Agents
Review Biomol Ther 27(2), 127-133 (2019) Streptomyces Cytochrome P450 Enzymes and Their Roles in the Biosynthesis of Macrolide Therapeutic Agents Myung-A Cho, Songhee Han, Young-Ran Lim, Vitchan Kim, Harim Kim and Donghak Kim,* Department of Biological Sciences, Konkuk University, Seoul 05025, Republic of Korea Abstract The study of the genus Streptomyces is of particular interest because it produces a wide array of clinically important bioactive molecules. The genomic sequencing of many Streptomyces species has revealed unusually large numbers of cytochrome P450 genes, which are involved in the biosynthesis of secondary metabolites. Many macrolide biosynthetic pathways are catalyzed by a series of enzymes in gene clusters including polyketide and non-ribosomal peptide synthesis. In general, Streptomyces P450 enzymes accelerate the final, post-polyketide synthesis steps to enhance the structural architecture of macrolide chemistry. In this review, we discuss the major Streptomyces P450 enzymes research focused on the biosynthetic processing of macrolide therapeutic agents, with an emphasis on their biochemical mechanisms and structural insights.

Arefa et al. BMC Microbiology (2021) 21:116 https://doi.org/10.1186/s12866-021-02175-5 RESEARCH ARTICLE Open Access Resistance‐guided isolation and characterization of antibiotic‐producing bacteria from river sediments Nowreen Arefa1, Ashish Kumar Sarker2 and Md. Ajijur Rahman1* Abstract Background: To tackle the problem of antibiotic resistance, an extensive search for novel antibiotics is one of the top research priorities. Around 60% of the antibiotics used today were obtained from the genus Streptomyces. The river sediments of Bangladesh are still an unexplored source for antibiotic-producing bacteria (APB). This study aimed to isolate novel APB from Padma and Kapotakkho river sediments having the potential to produce antibacterial compounds with known scaffolds by manipulating their self-protection mechanisms. Results: The antibiotic supplemented starch-casein-nitrate agar (SCNA) media were used to isolate antibiotic-resistant APB from the river sediments. The colonies having Streptomyces-like morphology were selectively purified and their antagonistic activity was screened against a range of test bacteria using the cross-streaking method. A notable decrease of the colony-forming units (CFUs) in the antibiotic supplemented SCNA plates compared to control plates (where added antibiotics were absent) was observed. A total of three azithromycin resistant (AZR) and nine meropenem resistant (MPR) isolates were purified and their antagonistic activity was investigated against a series of test bacteria including Shigella brodie, Escherichia coli, Pseudomonas sp., Proteus sp., Staphylococcus aureus,andBacillus cereus. All the AZR isolates and all but two MPR isolates exhibited moderate to high broad-spectrum activity. Among the isolates, 16S rDNA sequencing of NAr5 and NAr6 were performed to identify them up to species level. -

[E.Mail:[email protected] ] Received ; revised Antagonistic Streptomyces spp. were isolated from marine and mangrove sediment samples collected off Cochin, along the southwest coast of India. Sediment samples were pre-treated and following the soil dilution technique, samples were surface plated on starch casein agar and actinomycetes isolation agar. In the primary screening, 7.4% of presumptive actinomycetes (135 isolates) showed antibacterial activity against one or more bacterial fish pathogens and 3.7% of these cultures showed broad spectrum activity against the tested pathogens. Morphologically white powdery colonies with chalky white /grey appearance were selected as presumptive Streptomyces cultures. Isolates subjected to biochemical, physiological and 16S rDNA characters revealed the presence of three species of Streptomyces dominated by Streptomyces tanashiensis followed by S. viridobrunneus and S. bacillaris. Isolates characterized by 16S rDNA indicated the presence of 650 bp band in Streptomyces spp. Primary screening for activity against selected fish pathogens was done by a cross streak method using modified nutrient agar medium. Prominent isolates showing high zone of activity against the fish pathogens ranged 17-35 mm by the paper disc method. Enriched broth of selected isolates showing high antagonistic activity was screened for pharmacologically active agents revealed ethyl acetate fractions to be active against selected microbial pathogens.
